From f03163adc5b43b008bd19ea8b3ffcf6589857e85 Mon Sep 17 00:00:00 2001 From: Shiji Yang Date: Fri, 27 Sep 2024 09:51:22 +0800 Subject: [PATCH] mac80211: fix build error on kernel 6.6 The virtio_find_vqs() ABI has been changed since the 6.11 kernel. Switch back to using the old ABI to fix the build error: ../mac80211-regular/backports-6.11/drivers/net/wireless/virtual/mac80211_hwsim.c: In function 'init_vqs': ../mac80211-regular/backports-6.11/drivers/net/wireless/virtual/mac80211_hwsim.c:6632:31: error: array type has incomplete element type 'struct virtqueue_info' 6632 | struct virtqueue_info vqs_info[HWSIM_NUM_VQS] = { | ^~~~~~~~ ../mac80211-regular/backports-6.11/drivers/net/wireless/virtual/mac80211_hwsim.c:6637:16: error: too few arguments to function 'virtio_find_vqs' 6637 | return virtio_find_vqs(vdev, HWSIM_NUM_VQS, | ^~~~~~~~~~~~~~~ In file included from ../mac80211-regular/backports-6.11/drivers/net/wireless/virtual/mac80211_hwsim.c:38: ./include/linux/virtio_config.h:224:5: note: declared here 224 | int virtio_find_vqs(struct virtio_device *vdev, unsigned nvqs, | ^~~~~~~~~~~~~~~ ../mac80211-regular/backports-6.11/drivers/net/wireless/virtual/mac80211_hwsim.c:6632:31: error: unused variable 'vqs_info' [-Werror=unused-variable] 6632 | struct virtqueue_info vqs_info[HWSIM_NUM_VQS] = { | ^~~~~~~~ ../mac80211-regular/backports-6.11/drivers/net/wireless/virtual/mac80211_hwsim.c:6639:1: error: control reaches end of non-void function [-Werror=return-type] 6639 | } | ^ Signed-off-by: Shiji Yang --- ...x-init_vqs-build-error-on-kernel-6.6.patch | 30 +++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 package/kernel/mac80211/patches/build/235-fix-init_vqs-build-error-on-kernel-6.6.patch diff --git a/package/kernel/mac80211/patches/build/235-fix-init_vqs-build-error-on-kernel-6.6.patch b/package/kernel/mac80211/patches/build/235-fix-init_vqs-build-error-on-kernel-6.6.patch new file mode 100644 index 0000000000..4b0fe6003f --- /dev/null +++ b/package/kernel/mac80211/patches/build/235-fix-init_vqs-build-error-on-kernel-6.6.patch @@ -0,0 +1,30 @@ +--- a/drivers/net/wireless/virtual/mac80211_hwsim.c ++++ b/drivers/net/wireless/virtual/mac80211_hwsim.c +@@ -6629,6 +6629,7 @@ static void hwsim_virtio_rx_done(struct + + static int init_vqs(struct virtio_device *vdev) + { ++#if LINUX_VERSION_IS_GEQ(6,11,0) + struct virtqueue_info vqs_info[HWSIM_NUM_VQS] = { + [HWSIM_VQ_TX] = { "tx", hwsim_virtio_tx_done }, + [HWSIM_VQ_RX] = { "rx", hwsim_virtio_rx_done }, +@@ -6636,6 +6637,19 @@ static int init_vqs(struct virtio_device + + return virtio_find_vqs(vdev, HWSIM_NUM_VQS, + hwsim_vqs, vqs_info, NULL); ++#else /* Using the old ABI, copied from kernel 6.6 */ ++ vq_callback_t *callbacks[HWSIM_NUM_VQS] = { ++ [HWSIM_VQ_TX] = hwsim_virtio_tx_done, ++ [HWSIM_VQ_RX] = hwsim_virtio_rx_done, ++ }; ++ const char *names[HWSIM_NUM_VQS] = { ++ [HWSIM_VQ_TX] = "tx", ++ [HWSIM_VQ_RX] = "rx", ++ }; ++ ++ return virtio_find_vqs(vdev, HWSIM_NUM_VQS, ++ hwsim_vqs, callbacks, names, NULL); ++#endif + } + + static int fill_vq(struct virtqueue *vq)
